- The DOJ intervened in xAI’s lawsuit against Colorado’s AI anti-discrimination law, arguing it violates the 14th Amendment’s equal protection guarantee.
- A federal court already blocked Colorado from enforcing the law, set to take effect in June, until the case is resolved.
- The intervention signals the Trump administration is willing to deploy federal power to shield AI companies from state-level accountability.
Elon Musk’s xAI sued Colorado over its new AI law in April. Now the Trump administration has formally joined that fight.
The Justice Department intervened Friday in xAI’s lawsuit challenging Colorado’s HB 25-1009, which requires tech companies to prevent “algorithmic discrimination” in employment and other decisions. In its filing, the DOJ argued the law violates the 14th Amendment’s equal protection guarantee by effectively forcing companies to adopt certain viewpoints on discrimination—viewpoints the administration apparently doesn’t share. A federal district court had already blocked Colorado from enforcing the law until the case resolves.
The timing matters. The law was set to take effect in June. Without the injunction, xAI and other AI companies operating in Colorado would have had to prove their systems don’t discriminate in ways the state defines as unlawful—a bar Colorado set high, covering not just intentional discrimination but outcomes that correlate with protected characteristics.
What Colorado’s Law Actually Does
HB 25-1009—the “Colorado AI Act”—requires companies deploying “high-risk” AI systems to conduct bias audits, maintain documentation, and disclose when AI is making consequential decisions about employment, housing, or financial services. The goal is to prevent what civil rights groups call algorithmic discrimination: systems that produce discriminatory outcomes even without discriminatory intent.
xAI’s core argument, now echoed by the DOJ, is that the law is unconstitutional because it compels speech. By requiring companies to “guard against” discrimination, the law effectively forces AI developers to adopt a particular viewpoint on what constitutes discrimination—and how aggressively to prevent it. The DOJ’s brief, according to Fox News, frames this as an equal protection violation: the law treats AI companies differently based on what they produce, not who they employ.
Colorado officials have pushed back, noting the law applies equally to all employers and AI deployers regardless of political viewpoint. The law was passed with bipartisan support and is modeled on existing employment discrimination frameworks that courts have upheld for decades.
The case could set a precedent that determines whether states can regulate AI at all—or whether the federal government has preemption authority to shut down those efforts. As Bloomberg Law reported, the DOJ’s intervention is part of a broader effort by Trump’s AI Litigation Task Force to identify and challenge state AI laws deemed “onerous” to AI development. For more on xAI’s legal strategy, see Frontierbeat’s original report on the lawsuit.
The federal court’s next hearing is scheduled for June. Until then, Colorado can’t enforce the law—which means the question of whether state AI regulation can survive constitutional scrutiny remains unanswered.
